I'm presuming that this is a direct result of always running at max clock 1.6Ghz. I've been doing a little better lately adjusting clock speed manually, but I'm thinking of writing a daemon that will do the job automatically. It shouldn't take more than a day or so, but: 1) Does something like this already exist on FreeBSD? 2) Anyone else want it? I'd like to donate it for FreeBSD inclusion if it works well and any core person is interested. Thanks in advance, Jeff Katcher __________________________________ Do you Yahoo!? Yahoo!
